WordPress multisite is the same software that WordPress.com is built on. It allows you to create as many different WordPress sites as you want from a single database.

Some fun facts:

- WordPress.com hosts 37+ million sites using the WordPress multisite setup, which means they all run on one database.
- A regular WordPress site has 11 tables in the database. The first site in WordPress multisite network will also have 11 tables. Every site after that will add 9 tables to the same database which contains the data for the new site. So if you have 37+ million sites in your network you'll have 333 million tables in your database.

Here are the steps to configure a WordPress multisite install.

1. Make sure you have a domain in your hosting account. Either a root domain or an add-on domain. If you need help with Add-on domains watch this tutorial: https://www.youtube.com/watch?v=b4u7SUPB8ks

2. Download the WordPress files from WordPress.org and then upload them to the folder of your domain in your hosting account.

3. Create a MySQL database as you normally would.

4. Install WordPress as you normally would as well.

5. Add the below line of code to the wp-config.php file after WordPress has been installed:

define( 'WP_ALLOW_MULTISITE', true );

Paste that code right above the line that says:

/* That's all, stop editing! Happy blogging. */

Then save wp-config.php file.

6. Log out of and back into your WordPress site.

Go to Tools, then Network Setup. You'll be instructed to add some more code to your wp-config.php and some to your .htaccess file.
